Abstract (en)
[origin: EP3352328A1] A non-contact power feeding device (1) of the present invention includes multiple power feeding elements (power feeding coils 31) that are disposed spatially separated from one another in a movement direction, an AC power supply (2) that supplies AC power to the power feeding elements, multiple power receiving elements (power receiving coils 41) that are provided in a moving body (99) and that receive AC power in a non-contact manner, and a power receiving circuit (5) that converts the AC power received by the power receiving elements and that outputs to an electrical load (57), in which when a length of the power feeding elements in the movement direction is defined as LT, a separation distance between the power feeding elements is defined as DT, a length of the power receiving elements in the movement direction is defined as LR, and a separation distance between the power receiving elements is defined as DR, the relationship DT ‰¤ DR and the relationship (2 × LR + DR) ‰¤ LT are satisfied. According to this configuration, in at least one power receiving element, a favorable power receiving state is ensured and a large amount of AC power can be received at all times regardless of the position of the moving body, and therefore, a pulsing motion of the AC power received is suppressed, and it is possible to perform stable non-contact power feeding at all times.
